Personal Protective Clothing: Law Enforcement Officers’ Attitudes and Safety Behavior Assessments Toward High-Visibility Safety Apparel

Traffic related fatalities are one of the most common workplace hazards in the law enforcement community. They accounted for approximately 44% of all fatalities within the law enforcement occupational field between 2002 and 2011. Although many law enforcement officers’ deaths are due to being struck by vehicles, these could be prevented with the use of High-Visibility Safety Apparel (HVSA). The importance of raising traffic protective behavior compliance is largely overlooked by misperceptions in the workplace. Relatively few studies have examined HVSA wearing behaviors associated with social psychological human elements. It has still remained unclear as subjective or objective experiences. Proper assessment of law enforcement officers’ attitudes and safety behaviors are imperative in efforts to reduce traffic-related fatalities; andto improve the overall health and workplace safety in the law enforcement community. This study contributes to the research on law enforcement officers by providing information about what factors influence HVSA wearing decisions. It informs safety training officers and law enforcement organizations to develop successful training and practice programs that improve voluntary compliance

MODELING THE CONSUMER ACCEPTANCE OF RETAIL SERVICE ROBOTS

This study uses the Computers Are Social Actors (CASA) and domestication theories as the underlying framework of an acceptance model of retail service robots (RSRs). The model illustrates the relationships among facilitators, attitudes toward Human-Robot Interaction (HRI), anxiety toward robots, anticipated service quality, and the acceptance of RSRs. Specifically, the researcher investigates the extent to which the facilitators of usefulness, social capability, the appearance of RSRs, and the attitudes toward HRI affect acceptance and increase the anticipation of service quality. The researcher also tests the inhibiting role of pre-existing anxiety toward robots on the relationship between these facilitators and attitudes toward HRI. The study uses four methodological strategies: (1) incorporating a focus group and personal interviews, (2) using a presentation method of video clip stimuli, (3) empirical data collection and multigroup SEM analyses, and (4) applying three key product categories for the model’s generalization— fashion, technology (mobile phone), and food service (restaurant). The researcher conducts two pretests to check the survey items and to select the video clips. The researcher conducts the main test using an online survey of US consumer panelists (n = 1424) at a marketing agency. The results show that usefulness, social capability, and the appearance of a RSR positively influence the attitudes toward HRI. The attitudes toward HRI predict greater anticipation of service quality and the acceptance of the RSRs. The expected quality of service tends to enhance the acceptance. The relationship between social capability and attitudes toward HRI is weaker when the anxiety toward robots is higher. However, when the anxiety is higher, the relationship between appearance and the attitudes toward HRI is stronger than those with low anxiety. This study contributes to the literature on the CASA and domestication theories and to the human-computer interaction that involves robots or artificial intelligence. By considering social capability, humanness, intelligence, and the appearance of robots, this model of RSR acceptance can provide new insights into the psychological, social, and behavioral principles that guide the commercialization of robots. Further, this acceptance model could help retailers and marketers formulate strategies for effective HRI and RSR adoption in their businesses

Standardizing the Term “Strategy” in Retail and Business Curriculum

Strategy is a key concept in retail and business education. Yet, this important term has evolved to include many definitions, which can create confusion in the classroom environment. This paper proposes a standardized use of the term “strategy” in retail and business classrooms. It suggests a focused definition of strategy as “the principle that guides and inspires an organization to achieve optimum and long-term business performance by obtaining and sustaining competitive advantages.” It also outlines the development and definitions of strategy and discusses issues and concerns regarding the various definitions of strategy in academia. The study supports the need for clarification and efforts to incorporate standardized language into retail and business classroom settings. Keywords: Business, Competitive advantage, Curriculum, Education, Pedagogy, Retail, Strategy, Tactics.

Angiopoietin-1 is an apoptosis survival factor for endothelial cells

AbstractWe examined the effect of angiopoietin-1 (Ang1) on apoptosis in human umbilical vein endothelial cells (HUVECs). Ang1 (5–1000 ng/ml) dose-dependently inhibited apoptosis under a serum-deprived state. A significant apoptotic inhibition occurred with as low as 50 ng/ml. Two hundred ng/ml of Ang1 inhibited to approximately 50% of the control apoptotic rates for 96 h. Furthermore, an augmented antiapoptotic effect of Ang1 by the addition of 20 ng/ml vascular endothelial growth factor was observed. This Ang1-induced strong antiapoptotic effect in endothelial cells is a novel and intriguing finding and could be an additional description of Ang1-induced direct biological function

Quantitative Iodine-123 single-photon emission computed tomography/computed tomography for Iodine-131 therapy of an autonomously functioning thyroid nodule

Purpose Autonomously functioning thyroid nodules (AFTNs) are treated with iodine-131 (I-131) therapy, which increases the risk of permanent hypothyroidism; however, the risk can be reduced by separately estimating the accumulated activity for the AFTN and extranodular thyroid tissue (ETT). Methods A quantitative I-123 single-photon emission computed tomography (SPECT)/CT (5mCi) was performed in one patient with unilateral AFTN and T3 thyrotoxicosis. The I-123 concentrations measured at 24h were 12.26µCi/mL and 0.11µCi/mL in the AFTN and contralateral ETT, respectively. Thus, the I-131 concentrations and radioactive iodine uptake expected at 24h by 5mCi of I-131 were 38.59µCi/mL and 0.31 for the AFTN and 0.34µCi/mL and 0.007 for the contralateral ETT. The weight was calculated as CT-measured volume multiplied by 1.03. Results In the AFTN patient with thyrotoxicosis, we administered 30mCi of I-131, which would maximize the 24-h I-131 concentration in the AFTN (226.86µCi/g) and maintain a tolerable concentration in the ETT (1.97µCi/g). The percentage of I-131 uptake at 48h post I-131 administration was 62.6%. The patient achieved a euthyroid state at 14weeks and maintained the state until 2years post I-131 administration with an AFTN volume reduction of 61.38%. Conclusion The pre-therapeutic planning of quantitative I-123 SPECT/CT may enable a therapeutic window for I-131 therapy, which directs optimal I-131 activity to effectively treat AFTN while preserving the normal thyroid tissue.Key points Question: Is it feasible for I-123 SPECT/CT to be used for planning of I-131 therapy in an autonomously functioning thyroid nodule (AFTN)? Pertinent findings: The radioactive iodine uptake of the AFTN and extranodular normal thyroid tissue can be accurately estimated using the I-123 quantitative SPECT/CT. Implications for patient care: Patient-tailored I-131 therapy can be possible using the pre-therapeutic I-123 SPECT/CT-based planning in patients with AFTN.This study was supported by a grant from the Seoul National University Bundang Hospital Research Fund (Grant No. 02-2021-0050)
